I have used reveal.js and presenterm for simple work presentations and I enjoyed working with both. You’ll get a lot more flexibility and features from reveal, but presenterm is neat for certain kinds of presentations too.

Absolutely, they take their market cap for granted and have been making the user experience worse for years. I’m a pretty technical person so I switched to Linux for fun and software developer clout, but I’m so glad that the Linux desktop experience is getting good enough for everybody. I’ve had mostly an “it just works” experience on the major distros like Mint and Fedora, and honestly even the issues I’ve run into were simple enough to solve with some internet searches.

My condolences for the Windows issues. I hope you have a great time with Mint, that was my first daily-driver Linux distro. These days I seem to have fewer issues running games than my friends running Windows, and I hope it’s the same for you.
